Abstract
Major points of concern in implementing a wireless sensor network (WSN) are the network lifetime and energy utility within any delay tolerant network. Both these parameters define the success of the sensor network. The higher the expectancy of network Lifetime, the higher is the probability of acceptance of the network. Similarly, better the energy utilization in the network, better are the chances of success and implementation of the sensor network. Clustering is one such scheme adopted in WSN towards harnessing the best of above specified parameters for the network implemented. Most popular clustering techniques are the variants of LEACH protocol that facilitate cluster formation based on the proximity of an individual node to other nodes in the sensor network. These protocols are based on a single hop structure from the selected cluster heads in the network. This paper embarks on a multi-hop clustering algorithm that takes into consideration the spatial correlation between the nodes to form clusters and implements a highly energy efficient routing scheme which selects the multi-hop path in the network in a dynamic fashion.
Highlights
Wireless Sensor Networks find its application in almost all fields of study like agriculture, environment monitoring, seismological study, defense and security and even extending into today’s IoT [1]
Throughput is better using our proposed algorithm which is greater than LEACH and Enhanced LEACH by about 1.2 to 1.4 times
As we decrease the value of σ to 0.3, we see throughput increases from 1.8 to 2.3 times the throughput observed using LEACH and Enhanced LEACH
Summary
Wireless Sensor Networks find its application in almost all fields of study like agriculture, environment monitoring, seismological study, defense and security and even extending into today’s IoT [1] It generally consists of high density sensor nodes that are spatially distributed in a given area of interest. Many algorithms have adopted a clustering approach [2,3,4,5,6,7,8,9,10,11] with the cluster heads choosing a single hop data transfer mechanism to the sink.
